LS1021A shutdown after prolonged use

we encountered a problem with LS1021A during testing on our originally designed board, where the stream suddenly stops after about 1:53h. The problem occurred every time out of 3 tests. The log displays the following error which we didn't encounter before.


FAT-fs (mmcblk0p1): error, clusters badly computed (3746 != 3744)


The issue seems to be related to some memory overflow since it always occurs at the same time stamp. I am attaching the full log of this issue.


Second, less severe problem is the thermal shutdown setting. The default setting for LS1021A seems to be 95 degrees Celsius, which is well below the specification limit of 125 degrees. We would appreciate pointing in the right direction on how to change this setting since in our implementation the IC achieves higher temperatures than 95 degrees.
